3 Claims.

This invention relates to improvements in power presses.

An object of the invention is to provide an improved power press formattress factories which will compress the mattress lling material tothe proper thickness for placing in mattress casings or covers.

Another object of the invention is to provide an improved power operatedpress for compressing mattress filling material, and an adjustable stopassociated therewith for automatically stopping the operation of thepress when the press has moved downwardly the desired distance.

A further object of the invention is to provide a portable poweroperated press for compressing mattress filling fibers of various kindsto the desired thickness or for compressing any commodity that iscompressible, said press having an electric motor and connected gearreduction mechanism for operating the same.

Another object of the invention is to provide an improved portableelectrically operated gear reduction power press for compressingmattress lling material, together witha height regulator and anadjustable stop mechanism therefor.

Another object of the invention is to provide an improved motor operatedgear reduction mechanism for a powerV press, the same being highlyeiiicient in operation, and relatively inexpensive to manufacture andproduce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application:

Figure 1 is a plan view of the improved power press;

Figure. 2 is a sideY elevation of the improved power press;

Figure 3 is an end View of the improved power press, and

Figure 4 is a partial sectional View taken on the line 4 4 of Figure l.

Like characters of reference are used throughout the followingspecification and the accompanying drawings to designate correspondingparts.

In carrying out the invention, there is provided an improved power pressfor compressing mattress filling material comprising a substantiallyrectangular base frame generally denoted by the reference numeral I, thesame being formed of five and one-half inch steel beams and includingthe parallel spaced side members 2 and parallel spaced end members 3.

The four casters 4 will be suitably mounted atf the corners of the baseframe I to support the same in spaced relation above the floor 5.

The internally threaded socket fittings I5 will be supported at thecorners of the base framel I, and will be reinforced by the welded steelbracing strips 'I. Four vertically extending three inch tubes 8 will bescrewed into the socket fittings 6, and will guide the split slidingcollars 9 secured to the corners of the upper or compressing framegenerally indicated by the reference numeral I0.

The compressing frame I0 is substantially rectangular shaped, andincludes the oppositespaced side members II and the opposite spaced endmembers I2, preferably formed of five and one-half inch steel beams.

The four vertically disposed rack bars I3, I4, i5 and i6 are secured tothe four tubes 8, and have their teeth facing in the same direction.

A transversely extending motor supporting platform Il is secured betweenthe spaced side members II of the compressing frame I0. The outwardlyextending bearing supporting brackets I8 are secured to the outerl sidesof the side members II of the compressing frame I0, and support thespaced bearings I9 in which the shafts 20 are rotatably mounted. Thecogs or gears 2I will be secured to the opposite ends of the shafts 20and will intermesh with the rack bars I3, Ill, I5 and I6 to cause theraising of the compressing frame III when said shafts 20 are rotated inunison in one direction and lowering of the same when the shafts 20 arerotated in unison in the opposite direction.

A two to ve horse power electric motor 22 is mounted upon the platformI'I and'is connected by the conductor 23 and plug 24 to a suitablesource of electriccurrent'supply (not shown). The motor shaft 25 isconnected by means of the friction clutch 26 to the shaft 21 of a gearreduction mechanism 28 mounted on the platform Il. The driving shaft 28from the gear reduction mechanism 28 supports the spaced sprocket gears30 and 3|. Sprocket chains 32 and 33 are connected between the sprocketgears 30 and 3l and sprocket gears 34 and 35 on said shafts 20 fordriving them in the same direction.

Wood facing planks 36 are secured to the lower surface of thecompressing frame I0 by means of the fasteners (not shown). Similar woodfacing planks 38 are also secured to the upper surface of the base frameI in any desired manner.

The 9-gauge adjustable steel plates 39 and 40 are mounted at theopposite ends of the press and may be adjusted to varying heights atwhich the press may operate to support the mattress filling material inposition between the facing planks 36 and 38 -when the press is inactual operation.

A regulator rod 4l disposed adjacent one of the tubes 8 carries anadjustable trip finger 4I' to cooperate with an electric switchmechanism 42 on the compressing frame I0 to stop the operation of thepress at the desired and predetermined point, such switch mechanismbeing associated with the wiring of the electric motor 22 by means notshown.

Suitable lubricating ttings (not shown) will be provided as well asgrease retainers for properly lubricating the press.

From the foregoing description, it will be apparent that there has beendevised and provided a highly eflicient form of power operated pressused in mattress factories for compressing the mattress filling materialto the proper thickness for insertion within the mattress covers orcasings.

While the preferred embodiment of the instant invention has beenillustrated and described, it will be understood that it is not intendedto limit the scope of the invention thereto, as many minor changes indetail of construction may be resorted to Without departure from thespirit of the invention.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent of the United States is:

1. A power press comprising a base frame, a compression frame, forwardand rear pairs of vertical tubular guides secured to the compressionframe, each of said guides having a longitudinal slot in its forwardside, guide posts secured to and extending upwardly from the base frame,said tubular guides being slidably received on and embracing the guideposts, each of said guide posts having a longitudinal rack securedthereto which is received in the slot of the corresponding tubular guidewhich moves relatively to said rack, a pair of horizontal shaftsrotatably mounted on the compression frame, one of said shafts beingbetween said pairs of tubular guides and forward of the rear pair ,I

thereof with the other of said shafts being forward of the forward pairof tubular guides, pinions carried at the opposite ends of said shaftsin mesh with said racks, a drive shaft disposed between and parallel tosaid pair of shafts, a pair of drive sprockets on said drive shaft, adriven sprocket on each of said pair of shafts, and a drive chainentrained over each of said driven sprockets and one of said drivesprockets 4 whereby all of said sprockets are simultaneously driven inthe same direction.

2. In a power press comprising a base frame, a compression frame,upstanding guide posts on the base frame, said compression frame beingsupported by and guided for vertical movement by the guide posts, saidguide posts being cylindrical, a longitudinal rack projecting radiallyfrom each of said cylindrical guide posts, all of said racks havingtheir teeth facing in the same direction, tubular guides carried by thecompression frame, each of said tubular guides embracing and slidablyreceiving one of said guide posts and having a longitudinal slotslidably receiving the rack, whereby said tubular guides slidably guidesaid compression frame relative to the guide posts, pinions carried bythe compression frame engaging the racks, and power means simultaneouslydriving all of said pinions in the same direction.

3. A Yportable power operated mattress press comprising a brace frame,casters mounted to support the brace frame, socket members supported atthe corners of the base frame, tubular guide posts secured in saidsocket members, a movable guiding collar on each of said guide postshaving a longitudinal slot therein, a compression frame mounted on saidsplit collars, a rack bar on each of said guide posts and received inthe slot of the corresponding guide collar which moves relative thereto,gear wheels carried by the compression frame and meshing with the rackbars, and motor-driven means for simultaneously driving all of said gearwheels in the same direction for slidably propelling said compressionframe along said guide posts.
